While PyTorch is awesome, one thing it suffers from in my opinion is no "one way" to do things - I've found it difficult to take someones model and training code and tweak it so it fits in your code, compared to Chainer that has nice abstractions for a trainer, updaters, models, etc. PyTorch is easy to use and modify, but Chainer, and by extension cupy (a separate awesome project!) are really, really easy to work with.
